[Mozilla Enterprise] Stop Firefox from creating a new profile on upgrade

[Thane K. Sherrington]

It may be happening when I upgrade from an 32bit to a 64bit, but I'm not 
sure.  I'll check this on the next ones I do.

I don't think x64 should install in c:\program files (x86)\mozilla 
firefox because that would be really confusing.

So after reading this article, is it saying that I need to add

set MOZ_LEGACY_PROFILES=1

Prior to running the new install for the first time?

Does it need to be set permanently or just for the first run?

I think this article could be improved.  For instance this sentence:

"The changes to profile selection can be reverted by setting the 
environment variable MOZ_LEGACY_PROFILES."

Setting it to what?  There needs to be an example to make this clear.

I consider myself pretty knowledgeable about computers and Windows, but 
I'm completely lost by this explanation.

Is there a way to submit changes to the documentation pages?

I assume that MOZ_ALLOW_DOWNGRADE doesn't apply in my case, since I'm 
installing the same or later version.

Thanks for your help Mike.
